' s (ci. 10s-24) use of metal strips in finishing wall corners orv roof ridges together with their attendant disadvantages, as well as providing a neater external finish more in harmony with the building siding or roof shingles. "I

A primary object o@ this invention is an improved corner flnish strip having greater adaptability in use than the ridge rll disclosed in said patent.

A further object of the invention is the provision of a corner finish strip embodying'reinforcing elements thereby, substantially increasing its durability and pressure resisting properties over the ridge roll construction disclosed in the patent. n

A Still further provision of an improved corner finish strip which is capable of being readily applied to corners of varying angles and having provision for relatively wide surface contact with walls or roofs adjacent such corners.

A still further object of the invention is the provision of a corner nish strip which is of. relatively simple unitary construction and which is capable of ready manufacture at relatively lowA cost.

For a more complete understanding of the nature and objects ofthe invention, reference will be had,k to the following detailed description, taken in connection with the accompanying drawing, wherein:

Figure 1 isa transverse sectional view of the improved strip in accordance with a preferred embodiment thereof.

Figure 2 is a more or less diagrammatic perspective view of adjacent building walls showing the application of the improved strip to the ver--v tical cornermdened by such walls.

Figure 3 is a sectional perspective View of a roof showing the application of the improved strip to the ridge thereof.

Figure 4 connection between two adjacent strips.

Referring now in detail to the drawing by reference numerals and wherein like numerals object of the invention is` the is a longitudinal sectional view in;A the f. plane of line 4--4 in Figure 3 showing the lap designate like parts in the different views, S designates the improved strip in its entirety and which strip may be of any desired length as well as width.

The strip S as in the roll in saidpatent, includes a metallic reinforcing or backing plate or sheet I0 which may be of ordinary sheet iron and is of relatively thin gauge whereby it may readily be bent at the apex a of the strip S. The metallic sheet II) in conformity with the strip S as a Whole is bent intermediate its `opposite edges atk the apex a and is further bent adjacent its edges providing anges II substantially at right angles to the angularly related plane body portions I2 of the sheet. i

The thus formed metallic sheet I0 is covered on its inner surface with a relatively thin composition layer I3 and is also covered on its outer surface with a similar composition layer It.

The composition layers I3 and I4 are preferably of the same general nature a-s composition shingles or siding now in general use and due to their tacky character readily adhere to the metallic sheet Il) in' the -manufacture of the sheet S.

The layers I3 and Iii may be of. any desired thickness, the layer I4, however, preferably being somewhat thicker than the layer I3 and both layers conform to the shape of the metallic sheet It.

The inner composition layer I3'terminates at the edges of flange II but the outer layer It is continued at its opposite edges in parallelism with the body portions I2 of strip I for a substantial distance toward the apex a as indicated at I5.

The edge portions I5 of layer I4 extend parallel with and in spaced relation to the adjacent portions of the inner layer I3, thus providing channels in which are disposed longitudinal reinforcing members I6 which are desirably formed of wood but may well be of cellotex, paper, ply board 0r any bther desirable reinforcing ymate-- rial.

The adjacent portions of the composition layers I3 and I4 readily adhere to the engaged surfaces of the reinforcing members I6 and thereby hold same firmly in position.

As will readily be seen from Figures 1 and 3, the reinforcing members I6 are of substantial Width whereby the complete strip S is effectively reinforced including the portions thereof between the members I6 and the apex a.

Furthermore, `the portions I5 of theI composition layer III which extend toward the apex a for a substantial portion of the width of members I6 offer substantial piane surfaces for supporting engagement with building walls or roofs thereby providing effective seals against the Weather elements as well as supporting the strips most efliciently.

The strips S are assembled in end to end relation and in order to provide an effective seal of the joints between` the adjacent strips, the metallic sheet I0 as is indicated in Figure 4 extends beyond the adjacent ends of layers I3 and Il of one end of each strip S and terminates short of fthe adjacent ends of layers I3 and I4 of the opposite end of each strip S to provide lap joints I1.

Ihe improved strip constructed as disclosed is well adapted for use with building wall corners as indicated in Figure 2 or with roof ridges as lndicated in Figure 4.

When the strip is used as in Figure 2, the angle defined by the opposed plane body portions of the strip is a right angle as in Figure l for parallelism of such body portions with the adjacent walls WI which may be coveredwith-composition siding as indicated.

When the strip is intended for use with roof ridgesl as in Figure 3 the strip is bent at the apex a to provide vthe proper angle for parallelism of the said body portions as well as the portions I5 A with the opposite side of the roof R.. Thus while the finished strip is relatively rigid it is still capable of being bent at the apex a for use with corners of various angles and by the provision of the relatively wide plane surface contacting layer portions I5, the improvedstrip engages the wallsor roofs in such manner as to assure stability as well as an emcient seal against weather to the wall or roof joints covered by the strip.-

When the longitudinally alined lap joint connected strips S are applied as in Figure 2 or Figure 3 they provide a highly effective inish both from the standpoint of eiciency and 'appearance, and by the provision of the reinforcing members I6 the strips are capable of withstanding relatively heavy pressure impacts which they might be subjected to, particularly when used with building wallsas in Figure 2. The outer composition layer Il may be colored and lined to harmonize with various colors and forms of shingles and, siding whereby the use of such strips will in no way mar the desired external 'appearance of any particular side or roof of a building. While I have disclosed but a single specific embodiinent oi' my invention, such is to be considered as illustrative only, and not restrictive, the scope of the invention being defined in the subjoined claims.

What I claim and desire to secure by United States Letters Patent is:

l. A corner finish strip comprising a metallic sheet bent intermediate its opposed edges providing angularly related plane portions, a layer of composition material adhered to both the inner andI outer surfaces of the metallic sheet, Ythe 5 inner layer of material being coextensive in width with the metallic sheet, the outer layer of material extending beyond the edges of the metallic sheet and bent to'dene channels, and a reinforcing member supported within each of the 1g channels.

2. Thestructure denedl in claim 1 wherein said sheet and inner layer of material are bent at right angles to said plane portions to provide flanges at the opposed edges thereof, flanges be- 15 ing disposed between the outer layer of material and said reinforcing members.

3. A corner-nish strip comprising a metallic sheet bent intermediate its edges providing angularly related plane body portions meeting in 9,0 an apex, the plane body portions being extended toward their opposed free edges in the form ofl flanges at right angles thereto, a layer of composition material adhered to the inner surface of the metallic sheet and co-extensive in width 25 therewith, a layer of composition material adhered to the outer surface of the metallic sheet and being twice bent atfright angles toward its opposed edges defining longitudinal channels between same and the inner layer of material, and 30 a' reinforcing member longitudinally disposed within each of the channels with 4the adjacent edges of' the reinforcing members parallel with and in substantial spaced relation to said apex.

4. A corner nish strip comprising a relatively 35 rigid sheet of material including angularly related body portions meeting in an apex intermediate the width of the sheet, the opposed edges of the sheet being bent in the formation of channels, and a reinforcing member in each of the channels extending longitudinally thereof and with the adjacent edges of the reinforcing members parallel with and in substantial spaced relation to said apex.

5. A corner nish strip comprising a relatively rigid sheet of material including angularly related body portions meeting in an apex intermediate the width of the sheet, a reinforcing member of substantial width and thickness having one face thereof engaged with the inner wall of each body portion, the adjacent edges of the reinforcing members being parallel with and in substantial spaced relation to said apex, and the opposed edges of the sheet being twice bent at right angles in surrounding relation to the op- 56 posed edges and'portions of the other faces of the reinforcing members.
